Parker Heatless Modular Dryers - Four Key
Features to Guarantee Air Quality
OIL-X Filtration
Adsorption dryers are designed only for the reduction of water vapour and not liquid
water, liquid oil, water aerosols, oil aerosols, particulates or micro-organisms. Only by
using Parker OIL-X pre and after filtration can the treatment of these contaminants be
assured and air quality in accordance with all editions of ISO8573-1 be guaranteed.
Modular aluminium design
Aluminium extrusions are used throughout for drying chambers and
distribution manifolds. This design not only alows the dryer to be smaller,
more compact and lightweight, it allows the adsorbent desiccant material to
be filled using a speciallist technique called 'Snowstorm' filling which achieves
maximum packing density of the deisccant material (more adsorbent in a
smaller space).
Adsorbent desiccant material
Specially selected desiccant materials provide:
• Optimum adsorption and regeneration capacity - to ensure consistent dewpoint
• Low dusting - to prevent blockage of downstream filtration
• High crush strength - to prevent breakdown of the desiccant during operation
• High resistance to aggressive and oil-free condensate - for compatibility
with all types of air compressor, their lubricants and condensate
Snowstorm filled bed 'Snowstorm' filling method
Parker modular dryers use the 'Snowstorm filling' method
to fill the drying columns (or desiccant cartridges) with
adsorbent desiccant material.
Snowstorm filling:
• Achieves maximum packing density for the desiccant
material, fully utilising all of the available space

Heatless Modular Dryer - Operation
Adsorption dryers work on the principle of moisture always
migrating to the driest medium possible. Therefore, water
vapour is removed from compressed air by passing it over
an adsorbent desiccant material.
As the compressed air contacts the adsorbent At any one time, whilst one chamber is on-line,

utilise two chambers of desiccant material.
Heatless Modular Dryer Operation - Drying Cycle
The pre-filtered process air enters the dryer through the inlet and is directed into the on-line drying
chamber via the inlet valves.
(Modular models can be made up of either single or multiple drying columns, depending upon the range)
The compressed air is evenly distributed through the drying columns and passes over the adsorbent
desiccant material, reducing the water vapour content of the compressed air as it contacts the desiccant.
The dried process air then exits the dryer via the outlet check valves.

Heatless Modular Operation - Regeneration Cycle
At the start of the regeneration cycle, the exhaust valve of the dryer is closed and the off-line chamber is at full line
pressure. The air in the off-line chamber has a dewpoint equal to the air leaving the dryer.
The exhaust valve is then opened and the dry air within the chamber expands rapidly as it leaves the dryer via the
exhaust silencer, forcing water to be removed from the desiccant material.
Once the off-line chamber has depressurised, a continuous bleed of dried process air is directed into the off-line
desiccant bed for regeneration purposes. This regeneration air is also known as purge air.
With the exhaust valve open, the purge air expands from line pressure to atmospheric pressure and flows
downwards over the off-line desiccant material.
As the purge air at line pressure contains a fixed amount of water vapour, allowing it to expand means the purge air
becomes even drier, increasing its capacity to remove water from the saturated desiccant bed.

Heatless Modular Operation - Column Changeover
Before the on-line (drying) and off-line (regenerating) columns change over, the dryer exhaust valve, is
closed, allowing the purge air to repressurise the off -line columns. This ensures a consistent downstream
pressure and dewpoint when the drying chambers change over.

8Heatless Modular Dryers - EST & DS Energy
Saving Technologies
The energy required to regenerate the off-line desiccant bed in an
absorption dryer is constant, and based upon the assumption that the
dryer is operating at its full capacity and the desiccant bed requiring
regeneration has been fully saturated.
In reality, a dryer is rarely operating at full capacity all of the time,
for example during shift work and periods of low demand. Daily and
seasonal fluctuations in ambient temperature and humidity also change
the moisture loading placed upon the dryer.
Under such conditions, at the point in the drying cycle where the air flow
is switched from one drying chamber to the other, there is the potential
for drying capacity to remain in the desiccant material about to undergo
regeneration. As the energy used to regenerate this partially saturated
bed is based upon the assumption that the bed is fully saturated, more
energy (purge air) is consumed than is actually necessary.

9EST & DS Energy Saving Technologies
Operation
Parker CDAS / OFAS / FBP / MXS-DS / MXLE dryer ranges are all fitted as
standard with either the EST or DS Energy Saving Technologies (optional
for K-MT & KA-MT ranges). With these installed, the drying cycle remains
unchanged, however as the drying chambers are about to change over, the
EST / DS energy saving technology overrides normal operation to fully utilise
the drying capacity of the on-line desiccant material.
EST & DS Energy Saving Drying Cycle Extension
At the end of the regeneration cycle, and prior to column changeover,
the exhaust valve is closed to allow the purge air to re-pressurise the off-
line column, thus ensuring no loss of system pressure on changeover.
After re-pressurisation, both drying chambers will be at full line pres-
sure, no purge air is being used for regeneration and the dryer is in a
state of zero energy consumption.
Under normal operation, the drying chambers would now proceed to
change over automatically, however the EST / DS energy saving tech-
nologies incorporate a dewpoint sensor which is used to monitor the
pressure dewpoint of the compressed air leaving the dryer.
If the compressed air dewpoint is lower than the pre-set minimum dew-
point, the desiccant material is only partially saturated and has drying
capacity remaining within it.
The EST / DS energy saving technology will therefore override the stand-
ard control cycle and the dryer will continue to dry on the same column
with zero energy consumption for regeneration.
The dewpoint sensor constantly monitors the outlet pressure dewpoint
until the minimum set dewpoint has been achieved, at which point, col-
umn change over will occur.
The drying and regenerating cycle will then continue normally until the
next column changeover when the EST / DS energy saving technology
may again extend the drying cycle as dictated by the outlet pressure
dewpoint.
During the extension of the drying cycle, no purge air is consumed, sav-
ing compressed air, saving energy and saving money.

should they inadvertently occur.
Additional Energy Savings
Called Purge Economy, it is an energy saving feature
For installations where a Parker modular dryer is for Parker heatless dryers where the dryer is placed
installed between the air compressor and the air directly after the compressor and before the air
reciever, an additional energy saving feature built into receiver
the controller can also be implemented.
A Typical Installation
In a typical installation, the compressor will use a
pressure switch connected to the air receiver to sense
the system pressure.
When system pressure is achieved, the compressor
goes off load. If there is no system demand, i.e.
evenings and weekends, in theory the compressor
should remain off load, using no energy.
11Air loss
In this installation, even though there is no system
demand and the compressor is off load, the dryer will
continue to cycle, using purge air to regenerate the off-
line column.
As the dryer purges the off-line column, it will slowly
reduce the system pressure, eventually dropping to a
point where the compressor will come back on-load to
maintain pressure.
Purge Economy Operation
Purge economy is designed to stop the dryer
regeneration cycle when the compressor goes off load.
It uses a signal from the compressor to stop the dryer
regeneration cycle and close the exhaust valve. This
prevents unnecessary use of purge air, saving energy &
money. Once the system pressure drops due to actual
air demand, the compressor re-starts and the normal
drying cycle will be resumed.
